"Death and Love Amid the COVID-19 Pandemic": Effects of Pathogen Threats on Online Dating and Social Distancing From Life-History Strategy Perspectives.

Drawing from the terror management theory (TMT) and evolutionary perspectives of Life-History Strategy, a between-subject online experiment examined the interaction effects of pre-existing death anxiety, fear-inducing media content (coronavirus threat vs. gun violence threat vs. low threat mental disorder), and intrasexual competition for mates on online dating intentions and social distancing intentions during the COVID-19 pandemic. Results indicate the interaction effects of participants' pre-experimental death anxiety and different types of fear-inducing media content on perceived fear and intention to use online dating websites/apps as well as the interaction effects of pre-experimental intrasexual competitiveness and fear-inducing media content on social distancing intention in the context of online dating. Theoretical contributions to the terror management literature and practical implications for the online dating industry are discussed.

How intrasexual competitiveness shapes attitudes towards cosmetic surgery recipients.

Cosmetic surgery is extremely popular. Despite this, negative attitudes towards cosmetic surgery recipients prevail. Across two pre-registered studies, we examined whether intrasexual competitiveness explains these negative attitudes. Participants in Study 1 were 343 (mean age = 24.74) single heterosexual American women and participants in Study 2 were 445 (mean age = 19.03) single heterosexual Australian women. Participants in both studies were primed for either low or high intrasexual competitiveness. Contrary to our predictions, we found that priming condition did not influence participants' derogation and social exclusion of cosmetic surgery recipients. We did, however, find evidence for a 'relative attractiveness' halo effect: participants engaged in less derogation and social exclusion when they assumed cosmetic surgery recipients were more attractive than themselves. This suggests that 'pretty privilege' extends not only to women who meet conventional beauty standards, but also to those who are perceived as relatively closer to meeting these standards than the individual with whom they are engaging. Overall, we concluded that intrasexual competitiveness does not encourage the stigmatisation of cosmetic surgery recipients and examined alternative explanations for this phenomenon.

Do Transgender People Respond According to Their Biological Sex or Their Gender Identity When Confronted With Romantic Rivals?

This study examined the hypothesis that gender identity and biological sex represent independent modules and that transgender individuals respond to romantic rivals in line with their gender identity and not with their biological sex. Additionally, associations of jealousy with intrasexual competitiveness (ISC) and social comparison orientation (SCO) were explored. A total of 134 male-to-female and 94 female-to-male transgender individuals from Greater Buenos Aires, Argentina, responded to a questionnaire. In line with the predictions, female-to-male transgender individuals experienced more jealousy than male-to-female transgender individuals in response to a physically dominant rival, whereas male-to-female individuals experienced more jealousy than female-to-male individuals in response to a physically attractive rival. Regardless of their gender identity, in both groups social-communal attributes were the most jealousy-evoking characteristic. Overall, the results indicate that transgender individuals mainly respond in line with their gender identity and not in line with their biological sex when facing romantic rivals. In addition, transgender individuals high in ISC experienced relatively more jealousy in response to all rival characteristics, whereas SCO was only among male-to-female individuals associated with jealousy.

No Evidence for Associations between men's Salivary Testosterone and Responses on the Intrasexual Competitiveness Scale.

OBJECTIVES: Many previous studies have investigated relationships between men's competitiveness and testosterone. For example, the extent of changes in men's testosterone levels following a competitive task predicts the likelihood of them choosing to compete again. Recent work investigating whether individual differences in men's testosterone levels predict individual differences in their competitiveness have produced mixed results. METHODS: In light of the above, we investigated whether men's (N = 59) scores on the Intrasexual Competitiveness Scale were related to either within-subject changes or between-subject differences in men's salivary testosterone levels. RESULTS: Men's responses on the Intrasexual Competitiveness Scale did not appear to track within-subject changes in testosterone. By contrast with one recent study, men's Intrasexual Competitiveness Scale also did not appear to be related to individual differences in testosterone. CONCLUSIONS: Our results present no evidence for associations between men's testosterone and their responses on the Intrasexual Competitiveness Scale.

Intrasexual Competition and Height in Adolescents and Adults.

Intrasexual competition can be defined as the struggle between members of one sex to increase their access to members of the other sex as sexual partners. In our species, height is a sexually dimorphic trait probably involved in both intrasexual and intersexual selective processes. In the present research, we examined the relationship between height and individual differences in intrasexual competitiveness (i.e., the tendency to view same-sex interactions in general in competitive terms) in two populations of adolescents and adults of both sexes in Chile. According to our first prediction, among both adolescent and adult men, height was negatively associated with intrasexual competitiveness. In contrast, among women, height was not linearly nor quadratically related with intrasexual competitiveness as previously reported. Finally, adolescent men and women showed increased levels of intrasexual competitiveness compared to adult same-sex counterparts. Our results suggest that height is a relevant trait in mating competition among men. The lack of relationship between height and intrasexual competitiveness in women may suggest that the role of height in women mating competition may be more complex and mediated by other variables.
